Aave Faces Potential Losses of Up to $230 Million Following Kelp DAO Bridge Exploit

A recent exploit of the Kelp DAO and LayerZero bridge has put lending protocol Aave at risk of losing up to $230 million, pending the resolution of the situation. According to a report by Aave Labs and LlamaRisk, the incident involves rsETH, a liquid restaking token issued by KelpDAO, which relies on a bridge mechanism to transfer tokens between blockchains. An attacker manipulated this setup by forging a valid transfer message, resulting in the creation of new tokens without backing. The attacker then deposited these tokens into Aave as collateral and borrowed approximately $190 million in ETH and related assets. Aave has since taken steps to mitigate the risk, including freezing rsETH markets and halting new borrowing. The outcome now depends on how Kelp DAO handles the shortfall, with potential losses ranging from $124 million to $230 million. The exploit highlights the risks associated with cross-chain messaging and the importance of robust validation mechanisms. In response to the incident, users have withdrawn around $6 billion in total value locked from Aave, reflecting a broader pullback in the DeFi market. The report notes that Aave's DAO treasury holds approximately $181 million in assets, and discussions are underway to address potential losses.
